Abstract

Japanese school buildings have been changed from modern wooden structures to reinforced concrete structures after the Building Standard Law was established in 1950. Therefore, only a few modern wooden school buildings exist currently. Ensuring the seismic resilience of these wooden school buildings is essential for their preservation and longevity. In this study, a static pushover analysis was conducted for a modern wooden school building using a 3D frame model to simulate the relationship between lateral load and deformation. This 3D frame model was proposed based on the site investigation and the 2D frame model used in a previous study. From the analysis results, it is found that the bearing capacity was decided by the deformation capacity of the column-to-groundsill connection; therefore, reinforcement to these connections was required to improve the seismic performance of a modern wooden school building
